Recent neurophysiologic findings have shown that astrocytes play important roles in information processing and modulation of neuronal activity. Motivated by these findings, in the present research, a digital neuromorphic circuit to study neuron-astrocyte interaction is proposed. In this digital circuit, the firing dynamics of the neuron is described by… (More)

Recent neurophysiologic findings have shown that astrocytes (the most abundant type of glial cells) are active partners in neural information processing and regulate the synaptic transmission dynamically. Motivated by these findings, in the present research, a digital neuromorphic circuit to implement the astrocyte dynamics is developed. To model the… (More)

Process of purchase or supply is one of the most important factors of competitiveness of companies. Therefore, the supply managers of companies are expected to select and evaluate the suppliers, to provide the company needs. Evaluation of suppliers based on only one factor is not possible and it is necessary to adopt a method that several factors… (More)
